                <description>&lt;p&gt;The fourth wheezy based alpha release of Debian Edu was wrapped up
today.  This is the release announcement:&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;New features for Debian Edu 7.1+edu0~alpha3 released
2013-07-03&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;These are the release notes for for Debian Edu / Skolelinux
7.1+edu0~alpha3, based on Debian with codename &quot;Wheezy&quot;.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;About Debian Edu and Skolelinux&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu, also known as
Skolelinux&lt;/a&gt;, is a Linux distribution based on Debian providing an
out-of-the box environment of a completely configured school
network. Immediately after installation a school server running all
services needed for a school network is set up just waiting for users
and machines being added via GOsa², a comfortable Web-UI. A netbooting
environment is prepared using PXE, so after initial installation of
the main server from CD, DVD or USB stick all other machines can be
installed via the network. The provided school server provides LDAP
database and Kerberos authentication service, centralized home
directories, DHCP server, web proxy and many other services. The
desktop contains
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html&quot;&gt;more
than 60 educational software packages&lt;/a&gt; and more are available from
the Debian archive, and schools can choose between KDE, Gnome, LXDE
and Xfce desktop environment.&lt;/p&gt;

&lt;p&gt;This is the fourth test release based on Debian Wheezy. Basically
this is an updated and slightly improved version compared to the
Squeeze release.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Software updates&lt;/strong&gt;&lt;/p&gt;
&lt;ul&gt;
  &lt;li&gt;Dropped ispell dictionaries from our default installation.&lt;/li&gt;
  &lt;li&gt;Dropped menu-xdg from the KDE desktop option, to drop the Debian
    submenu.  It was not included with Gnome, LXDE or Xfce, so this
    brings KDE in line with the others.&lt;/li&gt;
  &lt;li&gt;Dropped xdrawchem, xjig and xsok from our default installation as
    they don&#39;t have a desktop menu entry and thus won&#39;t show up in the
    menu now that menu-xdg was removed.&lt;/li&gt;
  &lt;li&gt;Removed the killer system to kill left behind processes on
    multi-user machines, as it was no longer able to understand when a
    X display was in use and killed the processes of the active users
    too.&lt;/li&gt;
  &lt;li&gt;Dropped the golearn (from goplay) package as the debtags in wheezy
    are too few to make the package useful.&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;strong&gt;Other changes&lt;/strong&gt;&lt;/p&gt;
&lt;ul&gt;
  &lt;li&gt;Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
  &lt;li&gt;Multi-arch i386/amd64 USB stick ISO available.&lt;/li&gt;
  &lt;li&gt;Got rid of ispell/wordlist related debconf questions that showed
    up for some language options.&lt;/li&gt;
  &lt;li&gt;Switched to using http.debian.net as APT source by default.&lt;/li&gt;
  &lt;li&gt;Fixed proxy configuration on Main Server installations.&lt;/li&gt;
  &lt;li&gt;Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
    d-i is doing it.&lt;/li&gt;
  &lt;li&gt;Made sure root and user passwords were not left behind in the
    debconf database after installation on Main Server installations.&lt;/li&gt;
  &lt;li&gt;Made Roaming Workstation dynamic setup more robust and added draft
    script setup-ad-client to hook a Roaming Workstation up to a
    Active Directory server instead of a Debian Edu Main Server.&lt;/li&gt;
  &lt;li&gt;Update system to install needed firmware packages during
    installation, to work properly in Wheezy.&lt;/li&gt;
  &lt;li&gt;Update system to handle hardware quirks (debian-edu-hwsetup).&lt;/li&gt;
  &lt;li&gt;Corrected PXE installation setup to properly pass selected desktop
    and keymap settings to PXE installation clients.&lt;/li&gt;
  &lt;li&gt;LTSP diskless workstations use sshfs by default, allowing them to
    work without adding them to DNS and NIS netgroups for NFS access.&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;strong&gt;Known issues&lt;/strong&gt;&lt;/p&gt;
&lt;ul&gt;
  &lt;li&gt;No mass import of user account data in GOsa (ldif or csv)
    available yet (698840).&lt;/li&gt;
  &lt;li&gt;Artwork not enabled for all desktops.&lt;/li&gt;
&lt;/ul&gt;

                <title>Automatically locate and install required firmware packages on Debian (Isenkram 0.4)</title>
                <link>http://people.skolelinux.org/pere/blog/Automatically_locate_and_install_required_firmware_packages_on_Debian__Isenkram_0_4_.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Automatically_locate_and_install_required_firmware_packages_on_Debian__Isenkram_0_4_.html</guid>
                <pubDate>Tue, 25 Jun 2013 11:50:00 +0200</pubDate>
                <description>&lt;p&gt;It annoys me when the computer fail to do automatically what it is
perfectly capable of, and I have to do it manually to get things
working.  One such task is to find out what firmware packages are
needed to get the hardware on my computer working.  Most often this
affect the wifi card, but some times it even affect the RAID
controller or the ethernet card.  Today I pushed version 0.4 of the
&lt;a href=&quot;http://packages.qa.debian.org/isenkram&quot;&gt;Isenkram package&lt;/a&gt;
including a new script isenkram-autoinstall-firmware handling the
process of asking all the loaded kernel modules what firmware files
they want, find debian packages providing these files and install the
debian packages.  Here is a test run on my laptop:&lt;/p&gt;

&lt;p&gt;&lt;pre&gt;
# isenkram-autoinstall-firmware 
info: kernel drivers requested extra firmware: ipw2200-bss.fw ipw2200-ibss.fw ipw2200-sniffer.fw
info: fetching http://http.debian.net/debian/dists/squeeze/Contents-i386.gz
info: locating packages with the requested firmware files
info: Updating APT sources after adding non-free APT source
info: trying to install firmware-ipw2x00
firmware-ipw2x00
firmware-ipw2x00
Preconfiguring packages ...
Selecting previously deselected package firmware-ipw2x00.
(Reading database ... 259727 files and directories currently installed.)
Unpacking firmware-ipw2x00 (from .../firmware-ipw2x00_0.28+squeeze1_all.deb) ...
Setting up firmware-ipw2x00 (0.28+squeeze1) ...
# 
&lt;/pre&gt;&lt;/p&gt;

&lt;p&gt;When all the requested firmware is present, a simple message is
printed instead:&lt;/p&gt;

&lt;p&gt;&lt;pre&gt;
# isenkram-autoinstall-firmware 
info: did not find any firmware files requested by loaded kernel modules.  exiting
# 
&lt;/pre&gt;&lt;/p&gt;

&lt;p&gt;It could use some polish, but it is already working well and saving
me some time when setting up new machines. :)&lt;/p&gt;

&lt;p&gt;So, how does it work?  It look at the set of currently loaded
kernel modules, and look up each one of them using modinfo, to find
the firmware files listed in the module meta-information.  Next, it
download the Contents file from a nearby APT mirror, and search for
the firmware files in this file to locate the package with the
requested firmware file.  If the package is in the non-free section, a
non-free APT source is added and the package is installed using
&lt;tt&gt;apt-get install&lt;/tt&gt;.  The end result is a slightly better working
machine.&lt;/p&gt;

&lt;p&gt;I hope someone find time to implement a more polished version of
this script as part of the hw-detect debian-installer module, to
finally fix &lt;a href=&quot;http://bugs.debian.org/655507&quot;&gt;BTS report
#655507&lt;/a&gt;.  There really is no need to insert USB sticks with
firmware during a PXE install when the packages already are available
from the nearby Debian mirror.&lt;/p&gt;

                <title>The value of a good distro wide test suite...</title>
                <link>http://people.skolelinux.org/pere/blog/The_value_of_a_good_distro_wide_test_suite___.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/The_value_of_a_good_distro_wide_test_suite___.html</guid>
                <pubDate>Sat, 22 Jun 2013 07:00:00 +0200</pubDate>
                <description>&lt;p&gt;In the &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu /
Skolelinux&lt;/a&gt; project, we include a post-installation test suite,
which check that services are running, working, and return the
expected results.  It runs automatically just after the first boot on
test installations (using test ISOs), but not on production
installations (using non-test ISOs).  It test that the LDAP service is
operating, Kerberos is responding, DNS is replying, file systems are
online resizable, etc, etc.  And it check that the PXE service is
configured, which is the topic of this post.&lt;/p&gt;

&lt;p&gt;The last week I&#39;ve fixed the DVD and USB stick ISOs for our Debian
Edu Wheezy release.  These ISOs are supposed to be able to install a
complete system without any Internet connection, but for that to
happen all the needed packages need to be on them.  Thanks to our test
suite, I discovered that we had forgotten to adjust our PXE setup to
cope with the new names and paths used by the netboot d-i packages.
When Internet connectivity was available, the installer fall back to
using wget to fetch d-i boot images, but when offline it require
working packages to get it working.  And ad the packages changed name
from debian-installer-6.0-netboot-$arch to
debian-installer-7.0-netboot-$arch, we no longer pulled in the
packages during installation.  Without our test suite, I suspect we
would never have discovered this before release.  Now it is fixed
right after we got the ISOs operational.&lt;/p&gt;

&lt;p&gt;Another by-product of the test suite is that we can ask system
administrators with problems getting Debian Edu to work, to run the
test suite using &lt;tt&gt;/usr/sbin/debian-edu-test-install&lt;/tt&gt; and see if
any errors are detected.  This usually pinpoint the subsystem causing
the problem.&lt;/p&gt;

&lt;p&gt;If you want to help us help kids learn how to share and create,
please join us on
&lt;a href=&quot;irc://irc.debian.org/%23debian-edu&quot;&gt;#debian-edu on
irc.debian.org&lt;/a&gt; and the

list.&lt;/p&gt;

                <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Victor_Ni_u.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Victor_Ni_u.html</guid>
                <pubDate>Mon, 17 Jun 2013 10:50:00 +0200</pubDate>
                <description>&lt;p&gt;The &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and
Skolelinux&lt;/a&gt; distribution have users and contributors all around the
globe.  And a while back, an enterprising young man showed up on
&lt;a href=&quot;irc://irc.debian.org/%23debian-edu&quot;&gt;our IRC channel
#debian-edu&lt;/a&gt; and started asking questions about how Debian Edu
worked.  We answered as good as we could, and even convinced him to
help us with translations.  And today I managed to get an interview
with him, to learn more about him.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;I&#39;m a 25 year old free software enthusiast, living in Romania,
which is also my country of origin. Back in 2009, at a New Year&#39;s Eve
party, I had a very nice &lt;strike&gt;beer&lt;/strike&gt; discussion with a
friend, when we realized we have no organised Debian community in our
country. A few days later, we put together the infrastructure for such
community and even gathered a nice Debian-ish crowd. Since then, I
began my quest as a free software hacker and activist and I am
constantly trying to cover as much ground as possible on that
field.&lt;/p&gt;

&lt;p&gt;A few years ago I founded a small web development company, which
provided me the flexible schedule I needed so much for my
activities. For the last 13 months, I have been the Technical Director
of &lt;a href=&quot;http://ceata.org/&quot;&gt;Fundația Ceata&lt;/a&gt;, which is a free
software activist organisation endorsed by the FSF and the FSFE, and
the only one we have in our country.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
project?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;The idea of participating in the Debian Edu project was a surprise
even to me, since I never used it before I began getting involved in
it. This year I had a great opportunity to deliver a talk on
educational software, and I knew immediately where to look. It was a
love at first sight, since I was previously involved with some of the
technologies the project incorporates, and I rapidly found a lot of
ways to contribute.&lt;/p&gt;

&lt;p&gt;My first contributions consisted in translating the installer and
configuration dialogs, then I found some bugs to squash (I still
haven&#39;t fixed them yet though), and I even got my eyes on some other
areas where I can prove myself helpful. Since the appetite for free
software in my country is pretty low, I&#39;ll be happy to be the first
one around here advocating for the project&#39;s adoption in educational
environments, and maybe even get my hands dirty in creating a flavour
for our own needs. I am not used to make very advanced plannings, so
from now on, time will tell what I&#39;ll be doing next, but I think I
have a pretty consistent starting point.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
Edu?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Not a long time ago, I was in the position of configuring and
maintaining a LDAP server on some Debian derivative, and I must say it
took me a while. A long time ago, I was maintaining a bigger
Samba-powered infrastructure, and I must say I spent quite a lot of
time on it. I have similar stories about many of the services included
with Skolelinux, and the main advantage I see about it is the
out-of-the box availability of them, making it quite competitive when
it comes to managing a school&#39;s network, for example.&lt;/p&gt;

&lt;p&gt;Of course, there is more to say about Skolelinux than the
availability of the software included, its flexibility in various
scenarios is something I can&#39;t wait to experiment &quot;into the wild&quot; (I
only played with virtual machines so far). And I am sure there is a
lot more I haven&#39;t discovered yet about it, being so new within the
project.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
Edu?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;As usual, when it comes to Debian Blends, I see as the biggest
disadvantage the lack of a numerous team dedicated to the
project. Every day I see the same names in the changelogs, and I have
a constantly fear of the bus factor in this story.  I&#39;d like to see
Debian Edu advertised more as an entry point into the Debian
ecosystem, especially amongst newcomers and students. IMHO there are a
lot low-hanging fruits in terms of bug squashing, and enough
opportunities to get the feeling of the Debian Project&#39;s dynamics. Not
to mention it&#39;s a very fun blend to work on!&lt;/p&gt;

&lt;p&gt;Derived from the previous statement, is the delay in catching up
with the main Debian release and documentation. This is common though
to all blends and derivatives, but it&#39;s an issue we can all work
on.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;I can hardly imagine myself spending a day without Vim, since my
daily routine covers writing code and hacking configuration files. I
am a fan of the Awesome window manager (but I also like the
Enlightenment project a lot!),
&lt;a href=&quot;http://www.claws-mail.org/‎&quot;&gt;Claws Mail&lt;/a&gt; due to its ease of
use and very configurable behaviour. Recently I fell in love with
&lt;a href=&quot;https://launchpad.net/redshift&quot;&gt;Redshift&lt;/a&gt;, which helps me
get through the night without headaches. Of course, there is much more
stuff in this bag, but I&#39;ll need a blog on my own for doing this!&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
get schools to use free software?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Well, on this field, I cannot do much more than experiment right
now. So, being far from having a recipe for success, I can only assume
that:&lt;/p&gt;

&lt;ul&gt;

&lt;li&gt;schools would like to get rid of proprietary software&lt;/li&gt;

&lt;li&gt;students will love the openness of the system, and will want to
    experiment with it - maybe we need to harvest the native curiosity
    of teenagers more?&lt;/li&gt;

&lt;li&gt;there is no &quot;right one&quot; when it comes to strategies, but it would
    be useful to have some success stories published somewhere, so
    other can get some inspiration from them (I know I&#39;d promote
    them!)&lt;/li&gt;

&lt;li&gt;more active promotion - talks, conferences, even small school
    lectures can do magical things if they encounter at least one
    person interested. Who knows who that person might be? ;-)&lt;/li&gt;

&lt;/ul&gt;

&lt;p&gt;I also see some problems in getting Skolelinux into schools; for
example, in our country we have a great deal of corruption issues, so
it might be hard(er) to fight against proprietary solutions. Also,
people who relied on commercial software for all their lives, would be
very hard to convert against their will.&lt;/p&gt;

                <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Jonathan_Carter.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Jonathan_Carter.html</guid>
                <pubDate>Wed, 12 Jun 2013 09:50:00 +0200</pubDate>
                <description>&lt;p&gt;There is a certain cross-over between the
&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux
project&lt;/a&gt; and &lt;a href=&quot;http://www.edubuntu.org/&quot;&gt;the Edubuntu
project&lt;/a&gt;, and for example the LTSP packages in Debian are a joint
effort between the projects.  One person with a foot in both camps is
Jonathan Carter, which I am now happy to present to you.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;I&#39;m a South-African free software geek who lives in Cape Town. My
days vary quite a bit since I&#39;m involved in too many things. As I&#39;m
getting older I&#39;m learning how to focus a bit more :)&lt;/p&gt;

&lt;p&gt;I&#39;m also an Edubuntu contributor and I love when there are
opportunities for the Edubuntu and Debian Edu projects to benefit from
each other.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
project?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;I&#39;ve been somewhat familiar with the project before, but I think my
first direct exposure to the project was when I met Petter
[Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in 2005 in
London. They provided great feedback that helped the bootstrapping of
Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
it was great getting input from people who have been around longer. I
was also still very excitable and said yes to everything and to this
day I have a big todo list backlog that I&#39;m catching up with. I think
over the years the relationship between Edubuntu and Debian-Edu has
been gradually improving, although I think there&#39;s a lot that we could
still improve on in terms of working together on packages. I&#39;m sure
we&#39;ll get there one day.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux / Debian
Edu?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Debian itself already has so many advantages. I could go on about
it for pages, but in essence I love that it&#39;s a very honest project
that puts its users first with no hidden agendas and also produces
very high quality work.&lt;/p&gt;

&lt;p&gt;I think the advantage of Debian Edu is that it makes many common
set-up tasks simpler so that administrators can get up and running
with a lot less effort and frustration. At the same time I think it
helps to standardise installations in schools so that it&#39;s easier for
community members and commercial suppliers to support.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
Edu?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;I had to re-type this one a few times because I&#39;m trying to
separate &quot;disadvantages&quot; from &quot;areas that need improvement&quot; (which is
what I originally rambled on about)&lt;/p&gt;

&lt;p&gt;The biggest disadvantage I can think of is lack of manpower. The
project could do so much more if there were more good contributors. I
think some of the problems are external too. Free software and free
content in education is a no-brainer but it takes some time to catch
on. When you&#39;ve been working with the same proprietary eco-system for
years and have gotten used to it, it can be hard to adjust to some
concepts in the free software world. It would be nice if there were
more Debian Edu consultants across the world. I&#39;d love to be one
myself but I&#39;m already so over-committed that it&#39;s just not possible
currently.&lt;/p&gt;

&lt;p&gt;I think the best short-term solution to that large-scale problem is
for schools to be pro-active and share their experiences and grow
their skills in-house. I&#39;m often saddened to see how much money
educational institutions spend on 3rd party solutions that they don&#39;t
have access to after the service has ended and they could&#39;ve gotten so
much more value otherwise by being more self-sustainable and
autonomous.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;My main laptop dual-boots between Debian and Windows 7. I was
Windows free for years but started dual-booting again last year for
some games which help me focus and relax (Starcraft II in
particular). Gaming support on Linux is improving in leaps and bounds
so I suppose I&#39;ll soon be able to regain that disk space :)&lt;/p&gt;

&lt;p&gt;Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
git, Tomboy, KVM, VLC and LibreOffice. Recently I&#39;ve been torn on
which desktop environment I like and I&#39;m taking some refuge in Xfce
while I figure that out. I like tools that keep things simple. I enjoy
Python and shell scripting. I went to an Arduino workshop recently and
it was awesome seeing how easy and simple the IDE software was to get
up and running in Debian compared to the users running Windows and OS
X.&lt;/p&gt;

&lt;p&gt;I also use mc which some people frown upon slightly. I got used to
using Norton Commander in the early 90&#39;s and it stuck (I think the
people who sneer at it is just jealous that they don&#39;t know how to use
it :p)

&lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
get schools to use free software?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;I think trying to force it is unproductive. I also think that in
many cases it&#39;s appropriate for schools to use non-free systems and I
don&#39;t think that there&#39;s any particular moral or ethical problem with
that.&lt;/p&gt;

&lt;p&gt;I do think though that free software can already solve so so many
problems in educational institutions and it&#39;s just a shame not taking
advantage of that.&lt;/p&gt;

&lt;p&gt;I also think that some curricula need serious review. For example,
some areas of the world rely heavily on very specific versions of MS
Office, teaching students to parrot menu items instead of learning the
general concepts. I think that&#39;s very unproductive because firstly, MS
Office&#39;s interface changes drastically every few years and on top of
that it also locks in a generation to a product that might not be the
best solution for them.&lt;/p&gt;

&lt;p&gt;To answer your question, I believe that the right strategy is to
educate and inform, giving someone the information they require to
make a decision that would work for them.&lt;/p&gt;

                <title>Fixing the Linux black screen of death on machines with Intel HD video</title>
                <link>http://people.skolelinux.org/pere/blog/Fixing_the_Linux_black_screen_of_death_on_machines_with_Intel_HD_video.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Fixing_the_Linux_black_screen_of_death_on_machines_with_Intel_HD_video.html</guid>
                <pubDate>Tue, 11 Jun 2013 11:00:00 +0200</pubDate>
                <description>&lt;p&gt;When installing RedHat, Fedora, Debian and Ubuntu on some machines,
the screen just turn black when Linux boot, either during installation
or on first boot from the hard disk.  I&#39;ve seen it once in a while the
last few years, but only recently understood the cause.  I&#39;ve seen it
on HP laptops, and on my latest acquaintance the Packard Bell laptop.
The reason seem to be in the wiring of some laptops.  The system to
control the screen background light is inverted, so when Linux try to
turn the brightness fully on, it end up turning it off instead.  I do
not know which Linux drivers are affected, but this post is about the
i915 driver used by the
&lt;a href=&quot;http://www.linlap.com/packard_bell_easynote_lv&quot;&gt;Packard Bell
EasyNote LV&lt;/a&gt;, Thinkpad X40 and many other laptops.&lt;/p&gt;

&lt;p&gt;The problem can be worked around two ways.  Either by adding
i915.invert_brightness=1 as a kernel option, or by adding a file in
/etc/modprobe.d/ to tell modprobe to add the invert_brightness=1
option when it load the i915 kernel module.  On Debian and Ubuntu, it
can be done by running these commands as root:&lt;/p&gt;

&lt;pre&gt;
echo options i915 invert_brightness=1 | tee /etc/modprobe.d/i915.conf
update-initramfs -u -k all
&lt;/pre&gt;

&lt;p&gt;Since March 2012 there is
&lt;a href=&quot;http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4dca20efb1a9c2efefc28ad2867e5d6c3f5e1955&quot;&gt;a
mechanism in the Linux kernel&lt;/a&gt; to tell the i915 driver which
hardware have this problem, and get the driver to invert the
brightness setting automatically.  To use it, one need to add a row in
&lt;a href=&quot;http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/i915/intel_display.c&quot;&gt;the
intel_quirks array&lt;/a&gt; in the driver source
&lt;tt&gt;drivers/gpu/drm/i915/intel_display.c&lt;/tt&gt; (look for &quot;&lt;tt&gt;static
struct intel_quirk intel_quirks&lt;/tt&gt;&quot;), specifying the PCI device
number (vendor number 8086 is assumed) and subdevice vendor and device
number.&lt;/p&gt;

&lt;p&gt;My Packard Bell EasyNote LV got this output from &lt;tt&gt;lspci
-vvnn&lt;/tt&gt; for the video card in question:&lt;/p&gt;

&lt;p&gt;&lt;pre&gt;
00:02.0 VGA compatible controller [0300]: Intel Corporation \
    3rd Gen Core processor Graphics Controller [8086:0156] \
    (rev 09) (prog-if 00 [VGA controller])
 Subsystem: Acer Incorporated [ALI] Device [1025:0688]
 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- \
    ParErr- Stepping- SE RR- FastB2B- DisINTx+
 Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast &gt;TAbort- \
    &lt;TAbort- &lt;MAbort-&gt;SERR- &lt;PERR- INTx-
 Latency: 0
 Interrupt: pin A routed to IRQ 42
 Region 0: Memory at c2000000 (64-bit, non-prefetchable) [size=4M]
 Region 2: Memory at b0000000 (64-bit, prefetchable) [size=256M]
 Region 4: I/O ports at 4000 [size=64]
 Expansion ROM at &lt;unassigned&gt; [disabled]
 Capabilities: &lt;access denied&gt;
 Kernel driver in use: i915
&lt;/pre&gt;&lt;/p&gt;

&lt;p&gt;The resulting intel_quirks entry would then look like this:&lt;/p&gt;

&lt;p&gt;&lt;pre&gt;
struct intel_quirk intel_quirks[] = {
       ...
        /* Packard Bell EasyNote LV11HC needs invert brightness quirk */
        { 0x0156, 0x1025, 0x0688, quirk_invert_brightness },
       ...
}
&lt;/pre&gt;&lt;/p&gt;

&lt;p&gt;According to the kernel module instructions (as seen using
&lt;tt&gt;modinfo i915&lt;/tt&gt;), information about hardware needing the
invert_brightness flag should be sent to the
&lt;a href=&quot;http://lists.freedesktop.org/mailman/listinfo/dri-devel&quot;&gt;dri-devel
(at) lists.freedesktop.org&lt;/a&gt; mailing list to reach the kernel
developers.  But my email about the laptop sent 2013-06-03 have not
yet shown up in
&lt;a href=&quot;http://lists.freedesktop.org/archives/dri-devel/2013-June/thread.html&quot;&gt;the
web archive for the mailing list&lt;/a&gt;, so I suspect they do not accept
emails from non-subscribers.  Because of this, I sent my patch also to
the Debian bug tracking system instead as
&lt;a href=&quot;http://bugs.debian.org/710938&quot;&gt;BTS report #710938&lt;/a&gt;, to make
sure the patch is not lost.&lt;/p&gt;

&lt;p&gt;Unfortunately, it is not enough to fix the kernel to get Laptops
with this problem working properly with Linux.  If you use Gnome, your
worries should be over at this point.  But if you use KDE, there is
something in KDE ignoring the invert_brightness setting and turning on
the screen during login.  I&#39;ve reported it to Debian as
&lt;a href=&quot;http://bugs.debian.org/711237&quot;&gt;BTS report #711237&lt;/a&gt;, and
have no idea yet how to figure out exactly what subsystem is doing
this.  Perhaps you can help?  Perhaps you know what the Gnome
developers did to handle this, and this can give a clue to the KDE
developers?  Or you know where in KDE the screen brightness is changed
during login?  If so, please update the BTS report (or get in touch if
you do not know how to update BTS).&lt;/p&gt;

                <pubDate>Mon, 10 Jun 2013 22:50:00 +0200</pubDate>
                <description>&lt;p&gt;The third wheezy based alpha release of Debian Edu was wrapped up
today.  This is the release announcement:&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;New features for Debian Edu 7.0.0 alpha2 released
2013-06-10&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;This is the release notes for for Debian Edu / Skolelinux 7.0.0 edu
alpha2, based on Debian with codename &quot;Wheezy&quot;.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;About Debian Edu and Skolelinux&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu, also known as
Skolelinux&lt;/a&gt;, is a Linux distribution based on Debian providing an
out-of-the box environment of a completely configured school
network. Immediately after installation a school server running all
services needed for a school network is set up just waiting for users
and machines being added via GOsa², a comfortable Web-UI. A netbooting
environment is prepared using PXE, so after initial installation of
the main server from CD, DVD or USB stick all other machines can be
installed via the network. The provided school server provides LDAP
database and Kerberos authentication service, centralized home
directories, DHCP server, web proxy and many other services. The
desktop contains
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html&quot;&gt;more
than 60 educational software packages&lt;/a&gt; and more are available from
the Debian archive, and schools can choose between KDE, Gnome, LXDE
and Xfce desktop environment.&lt;/p&gt;

&lt;p&gt;This is the third test release based on Debian Wheezy. Basically
this is an updated and slightly improved version compared to the
Squeeze release.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Software updates&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;

&lt;li&gt;Iceweasel was updated from 10 to 17. (DSA 2699-1) 
&lt;li&gt;Updated libxv (DSA-2674), libxvmc (DSA-2675), libxfixes (DSA-2676), libxrender (DSA-2677), mesa (DSA-2678), xserver-xorg-video-openchrome (DSA-2679), libxt (DSA-2680), libxcursor (DSA-2681), libxext (DSA-2682), libxi (DSA-2683), libxrandr (DSA-2684), libxp (DSA-2685), libxcb (DSA-2686), libfs (DSA-2687), libxres (DSA-2688), libxtst (DSA-2689), libxxf86dga (DSA-2690), libxinerama (DSA-2691), libxxf86vm (DSA-2692), libx11 (DSA-2693), chromium-browser (DSA-2695), gnutls26 (DSA-2697), wireshark (DSA-2700), krb5 (DSA-2701), telepathy-gabble (DSA-2702) and subversion (DSA-2703). 
&lt;li&gt;Switched xrdp on thin client servers to use tightvncserver instead of xvnc4. 
&lt;li&gt;Now install software oscilloscope xoscope by default. 
&lt;li&gt;Now install music tools gtick, lingot and pianobooster by default. 

&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Other changes&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;

&lt;li&gt;The subnet-change script is now able to change all files needing a change on the main-server when changing the IP network used. 
&lt;li&gt;Updated translation of the installation. 
&lt;li&gt;New Romanian translation. 
&lt;li&gt;Fix security problem causing root and first user password to no longer show up in /var/cache/debconf/templates.dat. 
&lt;li&gt;Fix roaming workstation setup (Closed in libpam-mklocaluser/0.8, libpam-mklocaluser/0.8~deb7u1: #706753: libpam-mklocaluser: Fail to create local user during first login).
&lt;li&gt;Made roaming workstation setup more robust in non-Debian Edu environments. 
&lt;li&gt;New script debian-edu-bless to transform a Debian installation to a Debian Edu profile. 
&lt;li&gt;Adjust Iceweasel setup to improve performance when $HOME is on NFS. 
&lt;li&gt;More testsuite tests. 
&lt;li&gt;Make automatic proxy configuration more robust. 
&lt;li&gt;Adjust GOsa² GUI configuration. 

&lt;li&gt;Update thin client and diskless workstation setup to work with
LTSP in Wheezy.&lt;/li&gt;

&lt;li&gt;Diskless workstations now run out of the box -- no need to set
them up with GOsa².&lt;/li&gt;

&lt;li&gt;Update IMAP server setup. &lt;/li&gt;

&lt;li&gt;Fix login into Skolelinux Backup Tool (Closed in
slbackup-php/0.4.4-1: #700257: slbackup-php: Fails to submit correctly
entered password). &lt;/li&gt;

&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Known issues&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;

&lt;li&gt;DVD binary and source images are not yet ready.&lt;/li&gt;

&lt;li&gt;No mass import of user account data in GOsa (ldif or csv)
available yet (Open in gosa/2.7.4-4: #698840: gosa-plugin-ldapmanager:
missing import feature).&lt;/li&gt;

&lt;li&gt;Missing artwork for the KDE desktop (and probably a few others). &lt;/li&gt;

&lt;li&gt;KDE Debian submenu lacks icons (Closed: #502192: menu-xdg: invents
own icon names instead of using existing). This will remain
unfixed.&lt;/li&gt;

&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Where to get it&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;To download the multiarch netinstall CD release you can use&lt;/p&gt;

&lt;ul&gt;

                <pubDate>Wed, 5 Jun 2013 17:50:00 +0200</pubDate>
                <description>&lt;p&gt;Here is a call for help from the Debian Edu / Skolelinux project.
We have two problems blocking the release of the Wheezy version we
hope to get released soon.  The two problems require some with PHP
skills, and we seem to lack anyone with both time and PHP skills in
the project:

&lt;ol&gt;

&lt;li&gt;It is impossible to log into the slbackup web interface
  (slbackup-php) using the root user and password.  This is
  &lt;a href=&quot;http://bugs.debian.org/700257&quot;&gt;BTS report #700257&lt;/a&gt;.
  This used to work, but stopped working some time since Squeeze.
  Perhaps some obsolete PHP feature was used?&lt;/li&gt;

&lt;li&gt;It is not possible to &quot;mass import&quot; user lists in Gosa, neither
  using ldif nor using CSV files.  The feature was disabled after a
  major rewrite of Gosa, and need to be ported to the new system.
  This is &lt;a href=&quot;http://bugs.debian.org/698840&quot;&gt;BTS report
  #698840&lt;/a&gt;.&lt;/li&gt;

&lt;/ol&gt;

&lt;p&gt;If you can help us, please join us on IRC
(&lt;a href=&quot;irc://irc.debian.org/%23debian-edu&quot;&gt;#debian-edu on
irc.debian.org&lt;/a&gt;) and provide patches via the BTS.&lt;/p&gt;

                <title>Debian Edu interview: Cédric Boutillier</title>
                <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__C_dric_Boutillier.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__C_dric_Boutillier.html</guid>
                <pubDate>Tue, 4 Jun 2013 10:30:00 +0200</pubDate>
                <description>&lt;p&gt;It has been a while since my last English
&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and Skolelinux&lt;/a&gt;
interview last November.  But the developers and translators are still
pulling along to get the Wheezy based release out the door, and this
time I managed to get an interview from one of the French translators
in the project, Cédric Boutillier.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;I am 34 year old. I live near Paris, France. I am an assistant
professor in probability theory. I spend my daytime teaching
mathematics at the university and doing fundamental research in
probability in connexion with combinatorics and statistical physics.&lt;/p&gt;

&lt;p&gt;I have been involved in the Debian project for a couple of years
and became Debian Developer a few months ago. I am working on Ruby
packaging, publicity and translation.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
project?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;I came to the Debian Edu project after a call for translation of
&lt;a href=&quot;http://wiki.debian.org/DebianEdu/Documentation/Manuals&quot;&gt;the
Debian Edu manual&lt;/a&gt; for the release of Debian Edu Squeeze. Since
then, I have been working on updating the French translation of the
manual.

&lt;p&gt;I had the opportunity to make an installation of Debian Edu in a
virtual machine when I was preparing localised version of some screen
shots for the manual. I was amazed to see it worked out of the box and
how comprehensive the list of software installed by default was.&lt;/p&gt;

&lt;p&gt;What amazed me was the complete network infrastructure directly
ready to use, which can and the nice administration interface provided
by &lt;a href=&quot;https://oss.gonicus.de/labs/gosa/&quot;&gt;GOsa²&lt;/a&gt;.  What pleased
me also was the fact that among the software installed by default,
there were many &quot;traditional&quot; educative software to learn languages,
to count, to program... but also software to develop creativity and
artistic skills with music (&lt;a href=&quot;http://ardour.org/&quot;&gt;Ardour&lt;/a&gt;,
&lt;a href=&quot;http://audacity.sourceforge.net/&quot;&gt;Audacity&lt;/a&gt;) and
movies/animation (I was especially thinking of
&lt;a href=&quot;http://linuxstopmotion.sourceforge.net/&quot;&gt;Stopmotion&lt;/a&gt;).&lt;/p&gt;

&lt;p&gt;I am following the development of Debian Edu and am hanging out on
&lt;a href=&quot;irc://irc.debian.org/%23debian-edu&quot;&gt;#debian-edu&lt;/a&gt;.
Unfortunately, I don&#39;t much time to get more involved in this
beautiful project.&lt;/p&gt;
  
&lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux / Debian
Edu?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;For me, the main advantages of Skolelinux/Debian Edu are its
community of experts and its precise documentation, as well as the
fact that it provides a solution ready to use.&lt;/p&gt;
  
&lt;p&gt;I would add also the fact that it is based on the rock solid Debian
distribution, which ensures stability and provides a huge collection
of educational free software.&lt;/p&gt;
  
&lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
Edu?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Maybe the lack of manpower to do lobbying on the
project. Sometimes, people who need to take decisions concerning IT do
not have all the elements to evaluate properly free software
solutions. The fact that support by a company may be difficult to find
is probably a problem if the school does not have IT personnel.&lt;/p&gt;

&lt;p&gt;One can find support from a company by looking at
&lt;a href=&quot;http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp&quot;&gt;the
wiki dokumentation&lt;/a&gt;, where some countries already have a number of
companies providing support for Debian Edu, like Germany or
Norway. This list is easy to find readily from the manual. However,
for other countries, like France, the list is empty. I guess that
consultants proposing support for Debian would be able to provide some
support for Debian Edu as well.&lt;/p&gt;
  
&lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;I am using the KDE Plasma Desktop. But the pieces of software I use
most runs in a terminal: Mutt and OfflineIMAP for emails, latex for
scientific documents, mpd for music. VIM is my editor of choice.  I am
also using the mathematical software
&lt;a href=&quot;http://www.scilab.org/en/scilab/about‎&quot;&gt;Scilab&lt;/a&gt; and
&lt;a href=&quot;http://www.sagemath.org/index.html‎&quot;&gt;Sage&lt;/a&gt; (built from
source as not completely packaged for Debian, yet).

&lt;p&gt;&lt;strong&gt;Do you have any suggestions for teachers interested in
using the free software in Debian to teach mathematics and
statistics?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;I do not have any &quot;nice&quot; recommendations for statistics. At our
university, we use both &lt;a href=&quot;http://www.r-project.org/‎&quot;&gt;R&lt;/a&gt; and
Scilab to teach statistics and probabilistic simulations. For
geometry, there are nice programs:&lt;/p&gt;

&lt;ul&gt;

&lt;li&gt;&lt;a href=&quot;http://www.drgeo.eu/&quot;&gt;drgeo&lt;/a&gt; and
&lt;a href=&quot;http://edu.kde.org/applications/all/kig‎&quot;&gt;kig&lt;/a&gt; to do
constructions in planar geometry

&lt;li&gt;&lt;a href=&quot;http://www.geom.uiuc.edu/software/download/kali.html&quot;&gt;kali&lt;/a&gt;
to discover symmetry groups (the so-called wallpapers and frieze
groups), although the interface looks a bit old.&lt;/li&gt;

&lt;/ul&gt;

&lt;p&gt;I like also
&lt;a href=&quot;http://edu.kde.org/applications/all/cantor&quot;&gt;cantor&lt;/a&gt;, which
provides a uniform interface to SciLab, Sage,
&lt;a href=&quot;http://directory.fsf.org/wiki/Octave‎&quot;&gt;Octave&lt;/a&gt;, etc...&lt;/p&gt;
  
&lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
get schools to use free software?&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;My suggestions would be to&lt;/p&gt;

&lt;ul&gt;

&lt;li&gt;advertise the reduction of costs when free software is used.&lt;/li&gt;

&lt;li&gt;communicate about the quality of free software projects, using
    well known examples like Firefox, ThunderBird and
    OpenOffice.org/LibreOffice.&lt;/li&gt;

&lt;li&gt;advertise the living and strong community around the project.&lt;/li&gt;

&lt;li&gt;show that it is not more difficult to use than any other
    system.&lt;/li&gt;

&lt;/ul&gt;

                <title>Åpent møte på onsdag om bruken av Microsoft Exchange ved Universitetet i Oslo</title>
                <link>http://people.skolelinux.org/pere/blog/_pent_m_te_p__onsdag_om_bruken_av_Microsoft_Exchange_ved_Universitetet_i_Oslo.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/_pent_m_te_p__onsdag_om_bruken_av_Microsoft_Exchange_ved_Universitetet_i_Oslo.html</guid>
                <pubDate>Mon, 3 Jun 2013 14:00:00 +0200</pubDate>
                <description>&lt;p&gt;Jeg jobber til daglig ved &lt;a href=&quot;http://www.uio.no/&quot;&gt;Universitetet
i Oslo&lt;/a&gt;, en institusjon som lenge har vektlagt verdien av åpne
standarder og fri programvare.  Men noe har endret seg, og for en
liten stund tilbake annonserte USIT at dagens fungerende e-postsystemet
basert på fri programvare skulle byttes ut med Microsoft Exchange og
at Microsoft Outlook skulle bli den best fungerende men antagelig ikke
eneste støttede e-postklienten.  Annonseringen har ført til flere
protester og &lt;a href=&quot;http://folk.uio.no/dssantos/nooutlookatuio/&quot;&gt;en
underskriftskampanje&lt;/a&gt;, initiert av Diana Santos, der så langt 253
personer har signert.  Prosjektet
&lt;a href=&quot;http://www.usit.uio.no/prosjekter/nike/&quot;&gt;NIKE (Ny integrert
kalender/e-post)&lt;/a&gt; ble initiert for å se på mulige løsninger med
utgangspunkt i at en kombinert epost/kalenderløsning var påkrevd, og
prosjektet
&lt;a href=&quot;http://www.usit.uio.no/prosjekter/nike-implementasjon/&quot;&gt;NIKE-implementasjon&lt;/a&gt;
er igang med å rulle ut MS Exchange ved Universitetet i Oslo.&lt;/p&gt;

&lt;p&gt;For kun kort tid siden ble det annonsert at det blir et åpent møte
med ledelsen hos universitetet i Oslo med disse planene som tema:&lt;/p&gt;

&lt;p&gt;Tid: &lt;strong&gt;Onsdag 2013-06-05 kl. 10:00&lt;/strong&gt;
&lt;br&gt;Sted: &lt;strong&gt;9. etasje i Lucy Smiths hus (admin-bygget)&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt; Det kan være en god plass å stille opp hvis en som meg ikke tror
valget av Microsoft Exchange som sentral epostinfrastruktur er et
heldig valg for Norges ledende forskningsuniversitet, men at en er mer
tjent med å selv
&lt;a href=&quot;http://nuug.no/dokumenter/kronikk-friprog-itsikkerhet.shtml&quot;&gt;beholde
kontrollen over egen infrastruktur&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Saken har ført til endel presseoppslag så langt.  Her er de jeg har
fått med meg:&lt;/p&gt;
